    Abstract Background: Neurodevelopmental disorders (NDDs) impact both the development and functioning of the brain and exhibit clinical and genetic variability. RAP and RAB proteins, belonging to the RAS superfamily, are identified as established contributors to NDDs. However, the involvement of SGSM (small G protein signalling modulator), another member of the RAS family, in NDDs has not been previously documented.
    Methods: Proband-only or trio exome sequencing was performed on DNA samples obtained from affected individuals and available family members. The variant prioritisation process focused on identifying rare deleterious variants. International collaboration aided in the identification of additional affected individuals.

    Abstract Background: Members of two seemingly unrelated kindreds of Arab Moslem origin presented with pronounced early onset spastic paraparesis of upper and lower limbs, mild intellectual disability, kyphosis, pectus carinatum and hypertrichosis.
    Methods: The authors performed neurological and developmental examinations on the affected individuals. The authors conducted whole genome linkage and haplotype analyses, followed by sequencing of candidate genes; RNA and protein expression studies; and finally proof of principle investigations on knockdown morpholino oligonucleotide injected zebrafish.
    Results: The authors characterise a novel form of autosomal recessive complex hereditary spastic paraparesis (CHSP). MRI studies of brain and spinal cord were normal. Within a single significantly linked locus the authors ultimately identified a homozygous missense mutation c.1146A>T (p.K382N) in the vacuolar protein sorting 37A (Vps37A) gene, fully penetrant and segregating with the disease in both families. Mobility was significantly reduced in Vps37A knockdown morpholino oligonucleotide injected zebrafish, supporting the causal relationship between mutations in this gene and the phenotype described in the patients of this study.
    Conclusions: The authors provide evidence for the involvement of Vps37A, a member of the endosomal sorting complex required for transport (ESCRT) system, in upper motor neuron disease. The ESCRT system has been shown to play a central role in intracellular trafficking, in the maturation of multivesicular bodies and the sorting of ubiquitinated membrane proteins into internal luminal vesicles. Further investigation of mechanisms by which dysfunction of this gene causes CHSP will contribute to the understanding of intracellular trafficking of vesicles by the ESCRT machinery and its relevance to CHSP.
